To all whom t may concern.' j

Be it known that I, JAMES SEADLER, a citizen of the United States,residing at Sacramento, in the county of Sacramento and State ofCalifornia, have invented new and useful Improvements in a Tire, ofwhich the following is a specification. o

This invention relates to a vehicle tire and particularly to a core tireor filler which is adapted to be placed interior of an ordinary casing.

One 0f the objects of the present invention is to provide a simple,durable core tire or filler adapted to be placed interiorly of anordinary casing or tread and which will afford the desired degree ofresiliency and be the equivalent in function of a standard inflatedtire. Another object of the invention is to provide a core tire orfiller which is puncture proof and in conjunction therewith a pair ofmetal rings which will secure the casing and core tire together and alsopermit the tire as a whole to be applied to any standard form ofdemountable rim. Further objects will hereinafter appear.

The invention consists of the parts and the combination and constructionof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which- Figure 1 is a crosssection of an ordinary casing on line 1-1 of Fig. 2 showing theapplication of the invention.

Fig. 2 is a longitudinal section on line 2-2, Fig. 1.

Fig 3 is a side elevation of the tire partly in section. y

Fig. 4 is an interior view of an ordinary tire casing showing it out andperforated to receive the lacing.

Referring to the drawingsin detail, A indicates the tread portion of anordinary tire casing, and 2 the lower clencher edges. Adapted to beplaced interior of the casing is a core tire or ring which consists oftwo annular L-shaped sections 3 4. These sections are connected togetherat their inner edges by an annular continuous web 5 `while the upperinner edges are connected at intervals by cross-webs 6. They arefurthermore spaced apart or angularly projected as indicated at 7 toform a continuous annular channel 8 across which the connecting webs 6extend at intervals, and each section 3-4 is in turn reinforced andconnected with the inner side sections 7 by inter-spaced cross webs 9.

. Secured to the annular inner base section 5 of the core tir-e by meansof bolts 10 is a metal ring 11, the outer edges of which are turned upto form annular flanges 12. Interposed between the flanges 12 and thesides of the exterior tire casing A is a pair of tubular rings 13 andadapted to secure the casing, the core tire, the metal ring 11 and thetubular members 13 together as a unitary structure, is an annular metalclamping ring 14. This ring is secured to the inner ring 11 by means ofbolts 15, and is provided with a pair of annular grooves 16 which areshaped to receive the clenchers 17 on the tire casing. The outer edgesof the ring 14 are otherwise flattened aS at 18 to form a seat for thetire structure as 'a whole.

Any simple form of demountable rim7 or the one indicated at 19, may beemployed to secure the tire structure to the felly of a wheel; said rimbeing secured by locking lugs 20 and bolts 21.

The tire structure or filler here employed is particularly adapted foruse in connection with an old or worn tire casing, such as shown inFig. 1. The casing ordinarily em ployed assumes the inflated or extendedp0- sition indicated by dotted lines as at 22, see Fig 1. The treadportion of the tire is in this manner gradually worn down until theouter central wearing or tread surface is practically worn away. A pairof annular ridges 28 containing considerable rubber and consequentlywearing surface still remains on the casing and may therefore be used togreat advantage when the core tire or filler v here shown is employed.

In actual operation when it is desired toV j fit a worn casing for theuse here shown, it

is first necessary to slit the clencher beads in several places asindicated at 24, see Fig. 4. These slits may be spaced eight inchesapart lfor instance, and are provided for the purpose of permitting thetire to be expanded to fit the larger diameter of the ring 14; Theclencher beads are then perforated along each side as at 25 between eachslitted section to permit a lacing 26 to be applied as will hereinafterbe described. The core tire with the ring 11 bolted thereto is nextplaced within the casing to assume the position shown in Figyl.The'tubular rings are then inserted andthe cleneher beads are- Y 13, andthe side flanges 12 of the ring l1.

`The tire structure thus assembled is] finally completed by applying theclampingring lll. rFhis as previously described,

issecured to the ring l1 by means of bolts V15 and as these aregradually tightened it can readily be seen that the clencher beads will'be securely clamped between the rings 11- andll. rlhe tire may now beplaced on the demountable rim and is here locked against peripheralmovement by means of a plurality of radially disposed spring-actuat edlocking bolts'SO; the ordinary clamping lugs and bolts'21 being` finallyapplied to Ysecure' the' tire and rim fromflateral movement'withrelation to the felly ofthe wheel. The locking bolts V are carried bythe rim 19 landare secured therein by brackets 31 which are" applied forthis purpose and through 'which the bolts 30 -pass and into the plates.14 which are secured to ring lil, as in Figs. l and 2. Y

The method of attaching the rim 19 is not changed in any manner, andwill therefore not necessitate a reconstruction of the demo'untablestructure. t

An old and worn tirecasing mounted and filled with a coreV tireVconstructed` as here shown is to all practical purposes as resilient asan ordinary inflated casing. The annular ridges 23 left when the centerportion 1s worn away provides anew wearing surface and any pressureapplied on these points is transmitted to the sections 3 4 of theinnercore tire which in turn are supported by the tubular rings 13, andthe connecting "webs 6 and 9., The resiliency thus secured'deereasingthe resiliency or impairing theV is'practically the same asthatsecured by an ordinary pneumatic tire and as the structure as awhole'may4 be punctured wlthout structure, it 'can readily be seen thatthe eX- terior casing V may bel practically worn through before it 1snecessary to discard it.;

' The inner core tire preferably constructed of rubber, forms acontinuous flexible cushion forvrthe 1outer casingV andthe side seetions3-4 together with the tubular rings 13 form fillers toreshape the outercasing and'also tomaintain the sides of the casing in extended position.The'inner ring Mis preferably split at one point and the perforationsthrough which the bolts l5 pass Y,preferably elongated as shownin Fig. 2to permit a slight adjustment and drawingtd v gether of the ring when itis bolted to the core tire and ring Y1l.

VThe materials andV finish of the core tire and the coperating parts maybe such as the experience and judgment of the manufacturer may dictate.

l wish it understood that various changes in form, proportion and minordetails of construction may be resorted to within the scopeof theappended claims, and that l do not wish to limit myself to the specificdesign and construction here shown.

Havingthus described my invention, what I claim and desire to secure byLetters Patent isl. A tire core comprising two connected. flexible ringmembers, said ring members being L-shaped in cross section, andseparated toV form an annular exterior channel and a plurality ofinterspaced webs extend ing across said channel.
